Edit - Addendum: The video title is quite clickbait-y. The video doesn’t want to debunk any “serious” science, but rather investigates how badly done research with no reproducability or horrible statistical significance is used to influence the discourse in favour of regressive politics.
The introduction mostly showed the style of the creator. And it also showed published evopsych papers which the video was about to debunk. It didn’t even mention any “idiot on the internet”.
